To all whom iv may concern.-

Be it known that we, FRANK CJDQRMENT and GEORGE C. MoVoY, citizens of the United States of America, residing at Detroit, in the .county of Wayne and State of Michigan,

one of its objects is to provide a very simple and chea construction which is of such a size and s ape that the operator may manipulate and hold the same with one hand.

A further object is to provide an instrument which is very-compact in its construction and which has its 'discharge tube so arranged that it may be turned into engagement with the pump plunger and utilized to hold the same pressed inward so that less space will be taken up in packing.

It is also an object of the invention to so arrange the parts as to adapt the device to hold but a small quantity of the medicament at one time, thus preventing the liquid from becoming stale or rancid from long standing, and to so construct the device that all of the medicament contained therein may be atomized out.

Other objects of the invention are to provide a cheap and simple construction in which the parts may be readily taken apart for cleaning and repair, and to provide a very simple, cheap and efficient pump valve and other new and useful features the construction, arrangement and combination of parts, all as hereinafter more fully described, reference being had to the accompanying drawings, in which Figure 1 is a side elevation of a device embodying the invention and showing the parts in the position in which they are placed for erated with onehand; Fig. 4 is a detail of the packing the instrument in the smallest com pass; Fig. 2 is a central vertical section of the same with its parts in extended position; Fig. 3 is a side elevation illustrating the manner in which the device is held in use and opump valve showing an elevation of the ower side of the piston head.

As shown in the drawings 1 is a glass cup or receptacle for the liquid medicament which is formed with a deep annular depression 2 or groove in its side wall and provided with screw-threads at its upper end to receive a screw-cap 3 formed of sheet metal. A sheet metal disk or plate 4 of a diameter to fit within the cap is placed therein between it and the upper edge of the cup with a washer or gasket 5 of leather or other suitable material between the disk and edge to make a tight joint, and secured to or formed integral with the disk and depending within the axis of the cup is a tubular member opening through the disk at its upper end and forming a sheet metal pump cylinder 6 having a closed lower end or head 7 which is depressed to form a shoulder 8 in the cylinder to engage and limit the stroke of the pis-- ton and to also form an internal chamber 9 below the piston when the same is at the inner limit of its stroke.

The cylinder is suspended within the cup with itsinner end at a short distance from the bottom of said cup and secured to or formed integral with its lower end or head and extending diametrically across the same, is a tube 10, one end of which extends laterally from the cylinder with a slight downward curve and opens near the bottom adjacent to the point where the side and bottom of the cup meet. v

A very small hole 1 1 is provided in the cylinder head opening into the extreme opposite closed end of said tube and directly opposite in the outer wall of the tube is a large or stem at a short distance from its inner end which is externally screw-threaded, is the piston 15, consisting of a disk of sheet metal turned upward at its edge to form a peripheral stiffening flange l6 and secured to the lower face of said iston b a disk washer or nut 17 is the packing leather IS with its downwardly turned edge confined between the edge of the washer and the cylinder to make a tight joint.

A valve 19 to close the lower end of the tubular piston rod is provided and consists of a disk 20 of suitable flexible material such as thin leather, which is held in place over the IIO ' from the end of the tube slightly upon the outward movement of the piston and permit the air admitted to the stem through a small opening 23 in its outer end, to enter the interior of the cylinder. A coiled spring 24 interposed between the piston and bottom of cylinder normally holds said. piston at the extreme outer end of its stroke, and a series of holes 25 in the cap 3 permits the free entrance and exit of the air to the cylinder above the piston. I v

In the cap 3 at one side of the piston is a flanged opening and a corresponding opening is provided in the disk 4 within which latter opening is rigidly secured a tube or thimble 26 extending upward through the flanged opening in the cap and downward a short distance within the cup. A discharge or delivery tube 27 having a tapering end to fit within the outer end of the thimble is firmly held in place therein by the frictional engagement of the tapered end with the thimble'and the opposite end of said tube is provided with a suitable nasal tip 28, the tube being bent to the proper angle to insert the tip in the nostril of the user when the cup is held in the proper position for use, as shown in Fig. 3. This bend is such that the body of the tube extends substantially at right angles to the tapering end and therefore when the piston stem 13 is forced inward and said tube turned in its thimble to extend across the finger piece of the stem, said stem will be held in that position by the tube and the device may be packed in its assembled state in a 7 small space.

I the holes 11 and 12 and in passing through said holes draws a quantity of the medicament up through the tube 10 and discharges it into the cup together withthe air in a fine spray and this medicament laden air is I forced by the pressure thus created in the cup, outward through'the discharge tube and tip. The device is thus adapted to'contain only enough medicament for a few treatments as a larger quantity would cover the holes 11 and 12 and therefore the medicine never becomes stale .or spoiled from standing too long, and by reason of the tilting of the cup and the tube 10 extending laterally into the angle, all of the medicament may be atomized out.

Only a small amount of medicament being contained in the cup, said cup may be made of convenient size to hold in the hand and the air pump placed within it, thus making a very compact and convenient device.

If the atomizer be used by a lady or child having small hand, that person may place her thumb within the depression or groove 2 ,7 r

in the side of the cup.

By the arrangement of cap and disk which is tightly held thereby, the cylinder is centered and firmly held in the cup and the parts -may' be quickly and easily detached. .The

simplicity and cheapness of the construction of valve and other parts also add to the novelty of this invention.

' Having thus fully described our invention what we claim is:

1. In a device of the character described, the combination with a medicament receptacle, of a cylinder supported within the receptacle, a piston in the cylinder, means for actuating the piston, and a tube secured to the cylinder and opening at one end into the receptacle near its bottom and provided with a hole near its opposite end opening into the cylinder and a second hole opposite the first hole opening into the receptacle.
